SPEROSENS LHW-EOL LINEAR HEAT WIRE END OF LINE
LHW-EOL Linear Heat Wire End Of Line
The Sperosens LHW-EOL is a linear heat wire termination (EOL) and test unit. The
unit is compatible with most conventional fire panels as it allows fitment of user
supplied EOL resistors. Factory fitted compression glands ensure an IP65 rating
when installed.
Operation of the LHW circuit is simulated by an internal test button or external
activation of the magnetic reed switch.
APPLICATIONS:
- Linear heat wire installations in harsh environments
- Easy monitoring of LHW circuits
FUNCTIONALITY:
Compatibility:
- Conventional fire alarm panels
- Suppression release panels
- Addressable zone monitor units
Typical use cases:
- Combined with Spero LHW-I (Linear Heat Wire Interface unit)
- With a series fire resistor alone (range 330 Ohm to 2.7 KOhm)
APPLICATIONS:
- Linear heat wire installations in harsh environments
- Easy monitoring of LHW circuits
